Human Neurophysiology Laboratory

As shown to the left, a dedicated room for human neurophysiological recordings is equipped with 2 recording PCs and BIOPAC equipement. This set-up allows for simulataneous recordings of up to 8 channels of data sampling with real-time display of the recordings monitored by the experimenter. Data is digitally encoded and stored to allow detailed off-line analysis.

Shown to the right is the stimulation computer and bed for use during subject testing. The stimulation computer can present digital audio samples or images to subjects or be used to test cognitive performance such as memory skills or reading tasks. Subjects typically utilize the bed during EEG and sleep recordings.

Our equipment allows students to conduct the following human neurophysiological recordings:

GSR - galvanic skin resistance - measurements of human nervous system arousal using data samples from skin conductance, heart rate, and respiration also known as a polygraph test

This is an example of polygraph testing during a laboratory that stimulates arousal through olfactory odors. The subject's heart rate, respiration, and skin conductance are measured while sampling pleasant, neutral, and unpleasant stimuli.
